Issue with VR when changing TransferSyntax
Hi there, I've found something weird while using DCMTK. I've received in my PACS some Waveform based DICOM object (twelveLeadECGWaveformStorage) and i've seen that, when i use DCMTK tools in order to change the Transfer Syntax from ImplicitLittleEndian to ExplicitLittleEndian of the DICOM object the...

Planar configuration question
Hi there, Just a question regarding with compression and Planar Configuration: I've recently seen that when I'm compressing and decompressing (via JPEG) a DICOM file (using the DCMTK tools for that purpose) they don't keep the initial Planar Configuration. What I was doing is compressing it and deco...

Waveforms in DICOM
Hi there, I have seen you have been investigating and working in the implementation of waveform data (such as vital sign data) into DICOM and that you included a DCMTK module for this purpose called dcmwave, right? I was interested in this since one of our investigation projects we are working in go...

Hi Marco, thanks for your quick answer...yes, you are right the icon image is JPEG-embedded while the main dataset is uncompressed :shock: My answer here is, since i don't know a lot about it, is illegal to be in this situation (different encoding for different pixel data)? Shall both be of the same...

DCMCJPEG: Problem with Icon Image sequences
Hi there, I have found an issue (or that's what it seemed to me) while using the DCMTK tool for JPEG compressing: dcmcjpeg. The thing is that given an MG image (the problem is not focused in one image but generalized) that contain the element IconImageSequence (0088,0200), when i tried to compress i...

Issue adding Private tags
Hi there, I have been trying to add some private tags of my own using DCMTK to a DICOM file without success. I have firstly created a project with the mkdicbi.cxx file Then I modified the private.dic with the following: (0029,"XXX",00) UL MyGroupLength 1 (0029,"XXX",01) DS MinTem...

Overlays Issue
Hi there, I have reported some problems doing transformations with the DCMTK. Taking an image with Overlay tags, I managed to firstly compress it with dcmjpeg (doesn't care if it's Baseline, Lossless, Extended,...), then I decompress with dcmdjpeg and the final DICOM file result has lost the Tag (60...

JPEG Lossless compression on DCMTK
Hello, Basically the dcmjpeg module was developed with lossy JPEG compression in mind, so the code performs certain preprocessing operations that are visually (but not mathematically) lossless prior to applying the compression algorithm itself That's really a pitty. I need to use lossless JPEG compr...
